Aircraft Radio Frequencies used for Aviation
This page covers Aircraft radio frequencies used as aviation frequency bands. It covers the frequencies used in aircraft systems which include LOS, VOR, GS, TCAS, ATCRBS, DME, GPS L2, GPS L5, L1 etc. The table-1 mentions the same.
| Frequency range | Aircraft system | Radio spectrum |
|---|---|---|
| 105 to 140 MHz | LOS VOR(Very High Frequency Omnidirectional Range) VHF |
108.1 to 111.95 108 to 117.95 118 to 188 |
| 325 to 340 MHz | GS | 328.6 to 335.4 |
| 960 to 1250 MHz | TCAS(Traffic Alert and Collision Avoidance System) ATCRBS(Air Traffic Control Radar Beacon System) DME(Distance Measuring Equipment) GPS L2 GPS L5 |
1090 1030 962 to 1213 1227.60 1176.45 |
| 1565 to 1585 MHz | L1 | 1575.42 +/- 2 |
